A teacher began his class by holding up a glass with some water in it.  He held it up for all to see, and asked the students, " How much do you think this glass weighs?"

"50 g!" "100 g!" "125 g!" the students answered.

        "I really don't know unless I weigh it," said the teacher, "but my question is what would happen if I held it up like this for a few minutes?"

" Nothing! " the students said.

"OK. What would happen if I held it up like this for an hour?" the teacher asked.

"Your arm would begin to ache," said one of the students.

"You're right.  Now, what would happen if I held it for a day?"

"Your arm could go numb. Have to go to hospital for sure!" said another student. All the students laughed.

"Very good. But during all this, did the weight of the glass change?" asked the teacher.

"No." the students said.

"Then what caused the arm ache and the muscle (肌肉) stress?"

The students fell silent for a moment.

"Put the glass down!" said one of the students.

"Exactly!" said the teacher. "The problems of life are something like this. Hold them for a few minutes in your head, and it seems OK. Think of them for a long time and they begin to make you ache. Hold them even longer and you will not be able to do anything. It's important to think of the  challenges(挑战)  in your life, but it' s even more important to put them down at the end of every day before you go to sleep. That way, you are not stressed. You wake up fresh and strong and can deal with any challenge that comes your way!"

Remember to put the glass down today.
